Capacitors impact on sound?

[eetfuk]

I am just wondering how much impact different capacitor types (with same value) has on the sound.
Tried searching but found nothing intresting!

I've never tried any experimentation with this subject, but at least I can give you this link. http://members.aol.com/sbench102/caps.html

Old question, explained many times here and other places.

How did you search??

There is a lot of stuff on the web.  Some is ?  some is good.

Ok I'll chime-in with a reply, caps can make a difference but not much.

IMHO in signal passing area's (where your guitar signal passes through the cap) it comes down to using a decent Polyester or Polypropylene cap works best. I've done A/B testing like OD223's -vs- Mallory 150's before, and OD715P -vs- Solen etc and when you compare two decent caps the difference is negligable. Film-n-Foil can be better than Metalized Film ...but hardly noticable in a effect box build. In a high quality mixing board I would use nice Film-n-Foil caps.

Where your signal doesn't pass thought (like a low pass filter, or RF shunt) it makes hardly any difference, a ceramic works fine there if you wish.

Electrolytic caps can be all over the place, usually just look for a "low ESR" type and you'll do well.
